How Do I Measure an Angle in AutoCAD?

Measuring angles accurately is an essential skill when working with AutoCAD. Whether you are designing buildings, creating mechanical parts, or even drafting electrical schematics, being able to measure and depict angles correctly is crucial. In this tutorial, we will explore different methods for measuring angles in AutoCAD and how to use the various tools available to ensure accuracy in your designs.

Using the Angle command

To measure an angle using AutoCAD’s built-in tools, we can utilize the “Angle” command. This command allows us to measure the angle between two lines or objects with precision.

To start, follow these steps:

  • Select the “Angle” command from the AutoCAD ribbon or type “ANGLE” into the command line and press Enter.
  • Select the first line or object that forms one side of the angle.
  • Select the second line or object that forms the other side of the angle.
  • AutoCAD will display the measured angle on your screen.

Note: Make sure you select the lines or objects in the correct order to get an accurate measurement. The order of selection determines which side of the angle is considered as reference and which is considered as measured.

Using a Protractor Overlay

If you prefer a more visual approach to measuring angles, you can use a protractor overlay. This method involves importing a protractor image into AutoCAD and aligning it with your drawing to measure angles more intuitively.

Here’s how you can do it:

  1. Create or find an image of a protractor that suits your needs. Ensure it has a transparent background for better alignment.
  2. In AutoCAD, go to the “Insert” tab and select “Attach” or type “ATTACH” into the command line.
  3. Choose the protractor image file and click “Open.

  4. AutoCAD will prompt you to specify the insertion point of the image. Select a point on your drawing where you want to place the protractor overlay.
  5. Scale and rotate the image to match your drawing’s scale and orientation.
  6. Once aligned, you can measure angles by visually comparing your drawing lines with the protractor overlay.

Note: Remember to consider any scaling or distortion in your imported image when measuring angles accurately using this method.

Using Third-Party Plugins

If you find yourself frequently measuring angles or require more advanced angle measurement tools, consider using third-party plugins available for AutoCAD. These plugins offer additional features and functionalities beyond what is built-in in AutoCAD.

Here are some popular third-party angle measurement plugins:

  • AngleSnap: This plugin provides a snap feature that allows you to measure angles between lines accurately. It also offers customization options for snap increments and angle display formats.
  • CADprofi: Alongside other CAD tools, CADprofi includes an angle measurement tool that enables precise angle calculations with various measurement units supported.
  • CADtools: CADtools is a comprehensive plugin that includes an array of drafting and design tools, including advanced angle measuring capabilities with customizable settings.

By installing these plugins, you can enhance your AutoCAD experience by gaining access to specialized angle measurement features tailored to your specific needs.


In AutoCAD, measuring angles accurately is crucial for creating precise and professional designs. Whether you choose to use the built-in “Angle” command, a protractor overlay, or third-party plugins, understanding these methods will help you ensure accurate angle measurements throughout your projects. Experiment with different techniques and tools to find the one that suits your workflow best.

Remember: Accurate angle measurement leads to accurate designs!
